Drivers always nervously perceive differentthird-party noises and sounds that may occur in the vehicle. Sometimes whistling when driving a car does not promise anything serious. But sometimes it can indicate any serious damage to the engine. Let's look at what causes the whistle and how terrible it is at all.
Generator belt
The alternator belt is one of the mostcommon causes of unpleasant sound. At the same time, whistling occurs when the vehicle is moving, that is, under load. However, after gaining speed or progazovka it can pass. Also, if you hear a whistle when the car is moving and disappears when braking, the reason for this phenomenon is simple - belt slippage and strong wear.
Самостоятельно решить эту проблему легко.You do not even need to call in the service station. Just buy a new alternator belt and replace it. However, in the event that the car is under warranty, it is best to contact the service center. Also on some foreign cars mount the generator is quite complicated. Therefore, not everyone can take it off.
If a similar whistle when driving a carmanifested in rainy weather or after driving through a puddle, the reason may be even more banal - the belt becomes wet. In this case, you just need to wait until the part dries. After that, the whistle will pass by itself. Worry about this is not worth it.
Clutch problem
In modern cars can take place suchproblem like slipping clutch. Most often this is observed in cars that are very actively used in a city with a complicated driving mode: frequent stops, starting, sharp increases in speed, etc. The clutch suffers greatly. After all, it is subjected to heavy loads when it stops and starts off. Independently fix the problem of whistles associated with coupling, it is almost impossible without specialized knowledge and tools.
However, you can try to determine whether the whistle when driving a car is due to this problem. For this you need:
- Set the car on a small hill. This will create an effort when starting off. So you can give a large load on the motor at the beginning of the movement, which will allow you to hear the whistle better.
- Now you need to turn on the first gear and start off with a slow pressure on the gas pedal. So you can recognize the moment when the car starts to whistle.
- If there is a whistle at the beginning of the movementcar, that is, while grasping the clutch, then it says exactly about its malfunction. For confidence, you need to conduct a few more such tests. If in doubt, you can try to start with the second transmission. So the load on the clutch will increase, and the whistle will be heard more clearly.
Hear at speed a similar sound coming fromnode, unreal. Therefore, if the whistle is clearly manifested when starting off, but completely absent when driving at speed, then, most likely, the problem is precisely in the clutch.
Is it possible to repair?
Ремонтировать его придется только на СТО.Even with experience, it is difficult to understand modern gearbox and clutch systems. Therefore, it is better not to waste time, but to entrust such work to specialists. Most often you have to not repair, and change the clutch. However, for cars like this solution can cost a lot of money. For example, the whistle when driving a car "Chevrolet Cruze" managed to remove the replacement of the entire clutch system. So they write in some auto forums. However, this does not mean that this problem is common in these machines.
Engine support cushions
Даже современные моторы подвергаются сильным vibrations when the vehicle is moving. How does this manifest itself? Vibration loads are carried by engine pads, which are hard rubber products. Thanks to these details, the vibrations are extinguished, and the driver in the car practically does not feel them. Also, the cushions perceive the load associated with strikes on the undercarriage of the car. Such effects do not have a significant impact on the engine. However, the cushions may break down over time. One of the characteristic signs of this phenomenon is whistling while the car is moving. It can also occur if at least one of the pillows is loosely tightened.
How do pillows change?
Replacing the pillow is a complicated procedure.To do this, the engine is completely removed, suspended from the winch. Then unscrew the pillow, inspect and, if necessary, change to a new one. After that, the motor is put in place. In this case, it must be very accurately set, up to millimeters. If the installation of the power unit is not very accurate, then when cornering or when driving on a bad road, vibrations will occur in the engine. This makes it clear that it is almost impossible to replace the pillow yourself. This should be done only by professionals.
Timing Belt
Go ahead and consider the timing belt aspossible cause of whistling and rattling. Note that the belt itself can not whistle, but the whistle can come from the rollers and tensioners. To determine that the sound comes from the timing belt is quite difficult. At a minimum, you can start the engine and just listen to the place where the belt is located. If the whistle will be expressed and proceed precisely from this node, then you need to follow the SRT. After all, nothing can be done by yourself. As it was already written above, the problem here is not in the belt itself, but in the system, and nothing can be achieved by simply replacing the timing belt.
Other possible causes of whistling when driving a car
Whistling under the hood can cause power steeringsteering wheel. Especially often the problem occurs in domestic cars. After all, here the power steering system is made not the best way. Whistling can also drive the air conditioner or drive the coolant pump. Rattles and make sounds can be semi-axes if they freely walk in the CV joints. However, in this case, the car must not only whistle, but also twitch when starting off.
И вообще, издавать неприятный звук могут многие elements under the hood of the car, which accidentally unscrewed or struck with a sharp set of speed, hit a pit, a sharp start. Extremely unpredictable contacts can cause the car to whistle, and sometimes even experts at the service station cannot identify them. Quite often, the whistle comes simply because of the friction of some parts that do not play an important role in the system. Sometimes, outside objects may fall under the hood, which produce a characteristic sound during vibrations, etc. Therefore, before the start of extensive diagnostics at the service station, it is advisable to look under the hood and see if there are any external objects that could create a whistle.
What in the end?
Свист в двигателе нельзя оставлять и надеяться, that he will disappear on his own. Most likely, if you leave everything as it is, the malfunction of any system can lead to more serious problems with the motor in the future. Elimination of the whistle at an early stage will avoid the high costs of engine repair. Therefore, be sure to listen to the motor. If you find any strange whistle, then try to determine more precisely where it comes from. And if this fails, then go to the service station. Let the professionals deal with it.
However, some car owners do notdisturb third party noise from the engine. They successfully drive cars that not only produce an unpleasant whistle, but also jerk when driving, do not accelerate and slow down. What can we say about a whistle, which few people will pay attention! But still the vehicle is worth checking out.
